ALARM-CLOCK.

Specification of Letters Patent.

Patented Sept. 30, 1913.

Application filed April 10, 1912. Serial No. 689,889.

To all whom it may concern:

Be it known that I, GUSTAVE J. JAooARD, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York,

full, clear, and exact description.

My invention relates to an improvement in alarm clocks designedespecially for the benefit of deaf people; and the object thereof is toproduce an alarm cloek provided with the usual bell that rings at theappointed moment; and likewise with a lamp which can be caused to lightup at the same time, throwing upon thefa'ce of a person who has lost hissense of hearing a light intense enough to wake him;

My invention is further provided with appropriate controlling mechanismto enable the clock to be set so that either the bell or the lamp willbe actuated, or both actuated together, acording to the manner in whichthe parts are set.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which the same characters of reference indicatethe same parts in all the views.

Figure 1 is a front view of my improved alarm clock, showing part of theinterior mechanism; Fig. 2 is a front elevation of the controllingdevices; Fig. 3 is a side elevation of the parts shown in Fig. 2; Fig.

4 is a detail view, showing the electric cireuit for the lamp and themanner in which the same is closed; and Fig. 5 is a sectional viewshowing the mechanism for releasing the alarm actuating parts when theappointed time arrives, the view being taken along the line '55 of Fig.2, looking upward.

On the "drawings, the numeral 1 represents my improved alarm clock as awhole, and 2 the face of the same.

3 and 4 are the minute hand and the hour hand, respectively, and 5 is adial'having a pointer 6 mounted upon a spindle 7, having numbers fromone to twelve marked thereon, and the pointer 6 being set opposite haveinvented a new and Improved. Alarm-Clock, of which the following is a isout-turned as shown at 28. this dial these numbers, according to thehour at which the sleeper wishes to awake. This spindle 7 is mounted inthe framework of the body of the clock and can be manipulated by a knob.at the rear of the clock in the ordinary and usual way. Behind the faceof the clock and inside of the same it is provided with a disk 8 rigidlymounted upon the spindle 7, as shown in Fig. 2, and the disk 8 has anotch 9 in its rear face, which, when the hour arrives, receives a pin10 carried by a gear wheel 11. This gear wheel is loosely mounted uponthe spindle 7 so that it can be rotated thereon and slide along the sameas well, and it is engaged to be actuated by a pinion 12 on the spindleof the hour hand 13. The width of the face of this pinion 12 issuflicient to preserve the meshing engagement between the gears 11 and12 when the spindle 11 slides to a certain extent along the spindle 7.

14 is a spring member riveted at its upper end to a framework 15, whichsupports the motor mechanism inside of the clock, and this spring memberpasses behind the gear wheel 11, having an aperture which looselyreceives the spindle 7; and beyond this gear wheel 11 this spring member14 has a projection 16 for a purpose which will appear later. Theprojection 16 marks the extremity of the spring member 14, and connectedto this extremity is a piece of insulating fiber 17, supporting at itslower end a contact 18, to which is secured a conductor 19. 20 is asimilar strip of insulating fiber secured to the framework 15, andcarrying in its outer end a contact 21, connected to a conductor 22.These two conductors are in circuit with a source of electricity shownin Fig. 4,

reflector'hood 24.

25 is a locking lever which engages the projection 17 and holds thecontacts 18 and;

21 apart. It is pivoted at 27 on a'plate 26 secured to the frame 15,

I This outturned end 28 passes through a hole in the and its lower end Iend of an arm 29 mounted rigidly upon a spindle 31 supported by theplate 26, and

having secured thereon an operating arm 30 carrying at its outer end apin or stud 32.

As stated above, the arms 29 and 30 are fixed on the spindle 31, whichis rotatable in the plate 26, and on the inner end of this spindle ismounted an arm 33, having its end bent rearward, as shown in Fig. 3.This arm passes beneath the clapper arm 34 of an alarm bell 35, thisclapper arm being secured to a spindle 36 rotatably carried by theframework 15, and having an operating arm 37 projecting therefrom. Thisoperating arm is actuated by means of a toothed wheel, which is rotatedby a spring motor, as is usual in alarm clocks of this type. The numeral38 represents another arm projecting from the spindle 36; and 39represents a projection extending rearward from the spring member 14into engagement with the arm 38. When the locking lever 25 engages theprojection 16 on the spring member 14, it forces this lever rearwardly,and the projection 39 moves into the path of the arm 38 and prevents theclapper from ringing the bell, which .will be readily understood.

40 is a curved slot in the front of the body of the clock below the faceof the same,

and into this curved slot projects the pin 32.

41 is a mark adjacent the lower edge of the slot to indicate theposition of the pin when the lamp is to be lighted, Without releasingthe audible alarm device including the bell 35.

v The manner of operation of my alarm device will now be described.

Suppose one wishes to cause the alarm to be actuated at a given hour: Heturns the spindle 7 to bring the index pointer 6 to the correspondingnumber on the dial 5. This turns the disk 8 and causes the notch thereinto be set a certain angular distance from the pin 10-on the gear 11. Thegear 11 is rotated bythe pinion 12, and when the appointed hour arrives,the pin 10 will be carried into position to register with the notch 9;and when this happens the resiliency of the spring 14 will cause thelower end thereof carrying the projection 16 on the contact 18, to moveoutward; that is, toward the observer, referring to the position of theparts in Fig. 2. This movement of the spring member 14 will cause thegear 11 to slide along the spindle without getting disengaged from thepinion 12, and force the pin 10 into the notch 9 of the disk 8. In orderto permit t-his movement of the spring member 14, the arm 30 must bemoved to the left to throw the locking lever 25 away'fromthe-projection16. If

the lever 30 is moved to the position shown in Fig. 2, that is sofas tobring the pin 32 opposite the marl: 41v in the middle of the slot 40,the upper end of the arm '25 will be moved away from-the contact 16, but

the arm 33 will not be moved far enough to release the clapper arm 35.Consequently, when the spring member 14 moves forward, as described, theprojection 39 will move away from the arm 38, releasingthis arm, but thebell will be prevented from ringing by the arm 33. Hence, the movementof the spring member 14 can only result in allowing the contacts 18 and21 to come together, closing the circuit and illuminating the lamp 23.This throws a strong light on the sleepers face and wakes him. This modeof using my invention is intended especially for the benefit of deafpeople who, having lost the sense of hearing, could not be awakened bymeans of the sound of the bell 35. For persons having normal hearing thebell 35 can of course be used. This is accomplished by pushing the pin32 over to the extreme left end of the slot 40. By this movement the arm33 is moved out of obstructing position with respect to the clapper 34;but until the hour of waking arrives the projection 39 carried by thespring member .14 engages the arm 38 and holds the clapper 35 againstmovement. As soon as the pin 10 and notch 11 come into engagement, thespring member 14 moves forward as before, carrying the projection 39 outof obstructed position, releasing the clapper 34 and at the same timeclosing the electric circuit. The lamp now lights up and the bell 35rings at the same time,

and the sleeper not only wakes, but finds that the light has been madefor him.

From the above description it will be seen that my invention is adecided improvement upon the ordinary form of alarm clock which has noelectric connection to illuminate the room when the hour of risingapproaches. The lamp 23 can be an ordinary incandescent lamp andconnected to the conductors of an ordinary supply circuit, theseconductors leading to the switch formed bythe contacts 18 and 19. Eitherthe lamp can be caused to lightitself alone at a given hour, or the lampand the alarm can be set to be actuated together; and in the latter'case, after the alarm has rung itself out, the lamp 23 will continueburning as long as may be desired.

The pin 32 must, of course, be moved away from the right-hand end of theslot 40 in order to put the alarm clock in a position to operate at allat the time set; otherwise the locking lever 25 will hold the springmember 14 against movement, regardless of the relative position of therecess or "notch 9 and pin 10. Vhen the pin 32 is moved as far as themark 41, the lamp will light up at the required moment, and when it ismoved over to the other end of the slot boththe lamp and the bell willbe actuated together, when the controlling parts come into operativeposition.
